How to Mount Absolute Black Oval Narrow Wide Chainring:
There is a small mark (triangle shaped) on the inner circumference of the chainring. This mark Must sit behind the crank arm. The mounting procedure is identical for Deore, SLX, and XT cranks. Use the stock 1X Shimano M8 chainring bolts that come with a crank and Torque them to about 7Nm. IMPORTANT - if you are converting from a 2X chainring setup to a 1X and wish to mount a 30T absoluteBLACK ring, you need to purchase 1X bolts from Shimano for this crank because 2X bolts are too short. Other chainring sizes can use Shimano 2X bolts.

The oval (elliptical) chainring does not compromise the work of the clutch mechanism in the rear derailleur(video at the bottom). It also does not require a chain tensioner when used in the singlespeed application. Riding out of the saddle on the uphill will become more pleasant.

• Chain Compatibility Not compatible with Shimano HG+ chain
• Chainguide needed? No. But if you want one, the chain guide should have two teeth more capacity than the nominal oval ring size.
